Patent FI-974631-A (FI)
Inventor: PAPKOVSKI DIMITRI B
IPC: G01N/
Filed: 1997-12-29
Abstract: The invention relates to measuring sulphite and sulphur dioxide on the basis of the attenuation of the luminescence of a luminescent emitter. The luminescence emitters contain a hydrophilic, phosphorescent porphyrin dye which forms a complex with a hydrophilic carrier substance. On excitation, the porphyrin produces relatively long-lived fluorescence, both in the presence and in the absence of oxygen. The measurement solution, in which the emitter and the sample are placed, is sufficiently acid for dissolved sulphur dioxide to be formed, which sulphur dioxide is a powerful dynamic attenuator of the phosphorescence emitter. The degree of attenuation of the phosphorescence is compared with the corresponding attenuation of suitable calibration substances, with the result being the concentration of the analyte.

IPC: F23J15/00
Filed: 1999-07-08
Abstract: A method and an apparatus for reducing discharges of greenhouse gases, particularly carbon dioxide. Carbonaceous materials, wood, pieces of vegetation, products made therefrom, and especially vegetative and municipal wastes poorly suitable for energy production, are treated in such a way that the release of carbon dioxide back to the atmosphere is reduced and restrained substantially. This is accomplished such that an organic mass is carbonized by heating in a charring reactor (2) in an oxygen-free or limited-oxygen volume to charcoal (20), the amount of which is more than 50 % of the carbon content of the dry mass matter, and to a gas mixture (30), from which, after its burning and the recovery of primary energy, at least water vapour is condensed to water and the released heat is exploited on a counterflow principle in a countercurrent heater (1) in the heating and drying of materials to be fed into the process. The resulting charcoal (20) can be exploited in the purification of bodies of water and as soil conditioner.

Title: Process for chemical modification of growth hormones
IPC: A61K38/22
Filed: 1965-01-11
Abstract: Mammalian pituitary growth hormone is modified by treatment in aqueous solution with 2.5 to 10 parts by weight of cyanogen bromide at a pH of 1 to 3 and a temperature of 20 DEG  to 30 DEG C. for 1/2 to 16 hours, after which the modified hormone is recovered from the reaction mixture.  The completion of the reaction may be shown by estimation of increase in N-terminal amino-acid content, and of decrease in the ratio of methionine residues to homoserine lactone residues.  The product may be recovered by removal of cyanogen bromide and acid added to adjust the pH, by absorption of the mixture on a cross-linked dextran gel column followed by elution of the product, preferably together with dialysis of the solution, and then subsequent freeze drying or direct lyophilisation of the solution. The product is thus isolated as an amorphous powder.  Examples are given for the preparation of modified human and bovine growth hormones.

Abstract: 593,806. Dielectric heating. RADIO CORPORATION OF AMERICA. Jan. 19, 1945, No. 1592. Convention date, Jan. 31, 1944. [Class 39 (iii)] In a method of dehydrating fluids containing a material labile in the presence of heat, such as aqueous penicillin, lymph, plasma, mycellium and milk, the fluid is thermally agitated under sub-atmospheric pressure preferably 0.2-2 cm. of mercury, during heating by radio frequency electric fields, preferably, of not materially less than 100 megacycles per second. For bulk dehydration in a metal cabinet 1 connected through a condenser 35 to a vacuum pump, the fluid is contained in an electrode bowl 21, rotated on an insulator 22, about a similar electrode 27 having a coating 29 of a dielectric such as glass. The electrode 21 is capacitatively coupled by an electrode 31 to an oscillator 33. In another arrangement small quantities of the fluid are contained in a number of ampoules supported by racks in a cabinet as above, with a series of connected electrodes extending along each side of the racks, opposite electrodes registering with an ampoule and being such as to subject the whole of the agitated fluid to a radio frequency electric field. In a further arrangement, the fluid is contained in a flask directly connected to a vacuum pump and having a re-entrant base portion forming an annular space across which the radio frequency electric field is applied. Drying may be completed by evacuation alone. Thus for frozen fluids the radio frequency electric field may be removed soon after melting.

Title: Feed water regulator for steam boilers

Filed: 1957-01-16
Abstract: 842,207. Fluid-pressure servomotor control systems. ROUCKA, E. Jan. 16, 1957, No. 1646/57. Class 135. A feed water regulator for steam boilers conjointly controlled by water level in and the output of steam from the boiler comprises a balance beam 8 coupled to a control-valve 11 supplying pressure oil to a double-acting servomotor 13 which is connected by its rod 14 to a cable 15 and lever 16 to regulate the feed water valve 17. One end of the beam 8 carries a container 5 movable between stops 6 and connected by flexible pipes 2, 3 to the boiler steam and water spaces respectively so that the water level in the container corresponds to that in the boiler. The other end of the beam carries a counterweight 10 and is connected by a link 19 to a lever 20 which is in turn connected by a link 21 to a further lever 22 acted upon by the pressure difference on the two sides of a diaphragm 24. The diaphragm being connected by lines 25, 26 to opposite sides of a restriction in a flow-pipe which may carry the boiler steam, combustion air or flue gases. The lever 20 is fulcrumed on a roller 27, the position of which is variably adjustable along a guide beam 28 according to the position of the feed valve by a cam roller 35 mounted on the piston-rod and a cam 34 mounted on a pivoted lever 32 whilst the lever 22 is fulcrumed on similar rollers 29, the position of which may be adjusted along the beam 28 by a hand knob 30. The profile of the cam 34 is designed so that at all boiler loads the effect of the pressure difference acting on the diaphragm which is proportional to the square of the flow velocity is neither greater than nor less than the effect of the weight of the container and its contents which bears a linear relationship with the water level. When the flow signals are derived from the flow of combustion air the most favourable relationship between steam produced and combustion air consumed may not necessarily be maintained, which results in the load applied by the diaphragm and the lever system to the beam 8 being in error and the amount of water supplied to the boiler not corresponding with the steam supplied by the boiler resulting in a rise or fall in the normal water level. This higher or lower level results in an adjustment of the load acting on the beam 8 and hence through the link 19 on the balancing load so that the regulator stabilizes the water level at this higher or lower level and gives an indication to the stoker of incorrect firing which may then be put right. Regular fluctuations in the pressure of the feed water may be compensated for by suitable modification of the cam profile but irregular fluctuations thereof have a similar effect as an improper firing of the boiler resulting in a rise or fall in water level. A proper relationship between the water consumed as steam and the water supplied to the boiler is, however, still maintained. Instead of the regulator being operated by pressure oil it may be operated pneumatically or electrically or by a combination thereof.
